The TG-1 set pairs the 426 (9.5 inch) and 442 (12 inch) — two of the most-reached-for pliers in any plumber or homeowner toolbox. Both have Channellock’s PermaLock fastener that keeps the pivot from coming apart, undercut tongue-and-groove jaws that bite without rounding fasteners, and the long handles that let you hand-torque a fitting without a wrench.
This is the plier set you use on sink traps, water-heater connections, garden-hose fittings, exhaust clamps, and the random nut-or-bolt that’s bigger than your wrench set. Once you’ve owned a pair you understand why every American plumber says “channellocks” the way every Northeasterner says “frigidaire.”
Forged in Meadville, Pennsylvania at Channellock’s only factory — the same plant has been turning out these pliers since 1886.
